Problems with audio filesSupport

I just updated to android 2.2 and now when i try to add audio files to my card, the only way i can play them is to open the file through astro. Neither the stock player or cube player will show the files.

The stock player shows the files in the library but when I try to play the songs, it gives a message that i am missing a root file, or that the phone doesn't recognize the file type (mp3).

I moved an entire album over to the same location where all my previous albums are - music player is not aware that I added a new album at all. I cannot find the songs at all, but when I used Root Explorer to find the files manually, it played the album I moved over perfectly fine.

What encoding are you using to make your MP3, and are you using CBR / CBR?
